A total of 156 horses were analysed including the native breeds Małopolski (m), Wielkopolski (wlkp), Polish Half Bred Horse (pksp), and the foreign breeds Oldenburger (old), Holsteiner (hol) and Dutch Warmblood (kwpn). The competition results with distribution of penalty points as well as pedigree databases of Polish Horse Breeders Association and Polish Equestrian Federation were used. The data obtained was subjected to analysis of variance (ANOVA-GLM), and the differences between average values were determined with Tukey’s t-test. It was concluded that the native breeds obtained statistically worse results than foreign ones, proportionally to the level of competition difficulty. The propor- tion of native breeds among the participants of competitions decreased with increasing course difficulty and was statistically significant for the number of eliminations and clear rounds. The results allow a conclusion about the lower use value of native compared to foreign horse breeds for sports purposes. Key words: horse, breeding, show jumping, use value Show jumping is the most popular discipline among equestrian sports, which has been rapidly developing for the last few years (Aldridge et al., 2000). Equestrian competitions are not only exciting shows for the spectators and the scenes of sports rivalry but also constitute an important element of horse breeding practices (Koenen et al., 2004). The evaluation of genetic and phenotypic predispositions of horses for show jumping has been the subject of numerous publications (Koenen et al., 1995; Janssens et al., 1997; Aldridge et al., 2000; Wallin et al., 2003; Thorén et al., 2006; Ruhlmann et al., 2009). The development of this discipline is determined by a number *This study was financed from statutory activity DS-4. 538 S. Pietrzak and T. Próchniak of factors that should harmonise and complement one another. The possibility to obtain horses that are capable of meeting the requirements of currently constructed jumping courses is a fundamental condition. Currently, there are numerous breeds selected for improved jumping capabilities (Koenen et al., 2004). In the annually published rankings of the World Breeding Federation for Sport Horses (WBFSH) the top ranks are granted usually to such breeds as Holsteiner, Selle Français, Dutch Warmblood, Belgian Warmblood, Hanoverian and Westphalian (Ducro et al., 2007). Moreover, breeding a good jumping horse is conditioned by a number of other factors such as appropriate training and riders’ education system (Pietrzak, 2000; Gómez et al., 2006), as well as reasonable course construction (Sasimowski et al., 1986; Poll- mann-Schweckhorst, 2002). Well qualified riders and trainers are able to present all of the horse’s capabilities determined by its genotype and phenotype. The aim of the present work was to evaluate and compare the use value of native and some foreign horse breeds competing on the basis of the results obtained in show jumping tournaments. Material and methods Subjects were 156 horses and 151 riders who took part in Polish regional show jumping competitions in the territory of Lublin and Małopolska Equestrian Federa- tion in 2011 as part of nine events. The results of different breeds of horses obtained in normal competitions (not against the clock), competitions against the clock, com- petitions in two phases, in classes “L” (100 cm – height of fences) to “C” (130 cm – height of fences) were analysed. In total, 894 starts of the above mentioned horses and riders were analysed. Table 1.

The collected data was used to calculate the average number of penalties during a round (knocking down an obstacle; disobedience, refusal, run-out or resistance; ex- ceeding the time allowed) obtained by each breed of horses in the examined classes. The data was subjected to one-way analysis of variance with consideration of the Value of warm-blooded horses for show jumping 539 fixed effect of horse breed (ANOVA – GLM). The significance of differences be- tween the average values was determined with Tukey’s t-test for α=0.05. The authors did not consider the rider by horse interaction because the same pair (rider – horse) took part in around 99% of analysed starts. Table 2.

Moreover, statistical analysis of clear rounds characteristics and the eliminations of the studied horses was made within individual breeds. Table 3.

In “L” class competitions (Table 4) no significant differences between average values of penalty points obtained by each horse breed were registered. In “P” class better results (statistically significant difference) were obtained by the breeds Dutch Warmblood (2.36 pts.) and Holsteiner (1.60 pts.). In “N” class the weakest breed was Małopolski (12.13 pts.) and the best one was Dutch Warmblood (2.48 pts.). Average 540 S. Pietrzak and T. Próchniak results were obtained by Polish Half Bred Horses (4.47 pts.), Holsteiner (4.75 pts.) and Oldenburger (4.50 pts.). In “C” class the best results were obtained by Dutch Warmblood horses (1.93 pts.), whereas worse results were obtained by Małopolski (7.20 pts.) and Polish Half Bred Horses (5.98 pts.). Average results were obtained by Holsteiner horses (4.50 pts.) and Oldenburgers (3.58 pts.). It was noticed that statisti- cally the weakest results were obtained by the Małopolski breed in the competitions above “P” class, whereas Polish Half Bred Horses in “C” class competitions. Table 4.

The average proportion of clear rounds compared between groups of horses of different breeds was observed to decrease with increasing competition difficulty for the Polish Half Bred Horses breed, and to increase for Dutch Warmblood and Hol- steiner breeds (Table 5). It was also stated that a lower proportion of native breeds finish the competition without faults in comparison to foreign breeds. The proportion of horses which did not finish the competition for various reasons was particularly high for the Małopolski breed (around 16.67%) in “C” class (the most difficult in regional competitions), whereas for Dutch Warmblood and Hol- steiner breeds, no such case was registered in this class, similar to Oldenburger breed in “L” and “P” classes. The proportion of Polish Half Bred Horses which did not finish the competition in “C” class was relatively low at 0.91%. Among Małopolski horses the most frequent reason for elimination was the failure to jump non-typical fences (due to their construction or visual look): “liverpool” – 25%, “filler” – 21%, wall – 17%, “rainbow” ornamentation of the fence – 9%. The results obtained allow speculating that Małopolski horses are not completely predisposed to compete in higher class courses. This opinion is confirmed by practitioners (riders and trainers) and scientific research (Pietrzak et al., 2004). As is evident from the analysis of the data in Table 6, the proportion of native horse breeds decreases with increasing competition difficulty. This situation is par- ticularly clear for the Małopolski breed, whose proportion was around 24.07% in “L” class and around 6.90% in “C” class.
